A model for a homogeneous and isotropic spatially flat Universe, composed of baryons, radiation, neutrinos, dark matter and dark energy is analyzed. We infer that dark energy (assumed to behave as a scalar field) interacts with dark matter (either by the Wetterich model or by the Anderson and Carroll model) and with neutrinos by a model proposed by Brookfield et al. The latter is understood to have a mass-varying behavior. We show that, for a very softly varying field, both interacting models for dark matter give the same results. The models reproduce the expected red-shift performances of the present behavior of the Universe.
